✦ Synopsis

The study deals with the annual cycles of biomass, productivity and necrosis of the perennial wetland species Carex vesicaria and Phalaris arundinacea, and with the main growth parameters during the first part of 1979. The amplitudes of biomass variation differ, but other features of the development are largely the same. To detect the various climatic factors which determine the above-ground biomass dynamics, a proce. dure of multiple stepwise regression has been used. Regressions for annual trend and variation in production were obtained. They provide coarse models, which may be improved by including translocation to belowground organs.

In-vitro-grown cells of Mucuna pruriens, immobilized in calcium-alginate gels, were able to transform the precursor L-tyrosine into L-dihydroxyphenylalanine (L-DOPA). After the immobilization in alginate the plant cells released 90% of the produced L-DOPA into the medium; supplementation of the medi
